TechTatva’17 — Mechanize

Hover Rover
Anisha Das

Hover Rover’s didn’t come short of making its mark despite it’s debut in Tech Tatva this year. Based on prototypes, the event required the participants to construct a model hovercraft which would smoothly glide over both land and water.

The first round was a written test, which saw an impressive participant turn out of over 15 teams. Each team was given 45 minutes to attempt 30 multiple choice questions which tested their basic logical reasoning and technical concepts like friction and thrust. “The questions covered a wide range of themes from metallurgy, to automobiles,” said Akshay Singh, a first-year participant.

Based on a sample prototype, the participants were expected to come up with distinctive models. All participants were equipped with primary elements such as polystyrene for the model chassis. Including test drives, the models had to be up and ready within two and a half hours. The sample prototype provided was an elementary-looking working model made of polystyrene, propellers and a set of batteries. Even though the participants were required to follow the basic prototype provided, they had to incorporate individual propositions as well. Each team was allowed only 2 trial laps at the testing track. A 1.5m long testing track had been constructed for the final evaluation which had markings denoting each centimetre of deviation.

“The time taken to cover the track in a straight line is our judging criteria. For every centimetre of deviation, we deduce points. It is all about balance. This task can get quite complicated, but only imagination limits you,” said the event head, Sanket.

With a generous number of teams attending this event over two days, Air-o-Mania was a throwback to the ‘Best out of Waste’ competitions back in school. The preliminary round challenged the participants to build a prototype of a working air gun. They were also asked to use it in a game to aim at a pyramid of disposable cups. The room brimmed with activity from sawing to moulding to get the right mixture of the M-Seal clay. With candles lit to mould the PVC pipes to shape, it became inconvenient to keep the fans switched off due to the lack of ventilation in the room. Despite that, the preliminary round transitioned smoothly to the finals.

In the final round, an air-blower had to be devised to direct a ping pong ball through a maze filled with obstacles. Teams came up with innovative amends to their basic prototype.  After another two hours of construction, the prototypes were made and the participants were up to the challenge. Unfortunately, with motor failures and balls getting stuck in clingy grooves, the event concluded faster than expected for certain participants.

Overall, it was a light-hearted programme to be conducted which has an immense scope of learning. The event even saw an out-station team from AITM Bhatkal eagerly participating. Captained by the Category Head, Satwik Mohanty, and Event Head, Bharath Ravindranath, the organising team did a brilliant job to have the participants take back wonderful memories.

Based on the logistics of mechanics mixed with tinges of craftwork, Hydronomics by Mechanize aimed at designing hydraulic arrangements from stationery and ice-cream sticks. The objective of the event was to form a basic understanding of how machines work.

The first round provided participating teams with a small kit consisting of syringes, ice-cream sticks, paper clips, and glue. With this, they were to make a prototype that would elongate to lift objects, when provided hydraulic pressure through syringes. Alongside this, teams also took a fifty mark aptitude test which tested their logical reasoning skills and basic Physics knowledge. Although the organizers had prepared their own prototype for reference, participants were free to make their own designs and get creative, without compromising on efficiency. At the end of a busy two hours, the prototypes were tested based on height reached and weight sustained at a specific height.

The next round was held the very next day in the Basic Mechanics Workshop and got progressively more challenging. Qualifying teams were to make a hydraulic claw which would move linearly, as well lift objects for the purpose of transportation. Yet again, teams took inspiration from the organizers’ well-made prototype, while also displaying their creativity and efficient design. The prototypes were finally tested with three objects and three tries each, in a race against time to achieve victory.

Needless to say, the event head was quite pleased with the final outcomes of the event and gave a satisfactory feedback on the performance of the participants. The event sailed through swiftly, with minimal delays and splendid turnout.

The event took place in the PG CAD Lab, AB1. For the first round, various diagrams on a piece of paper were handed over to the participants to depict them on the eminent software CATIA with proper dimensions. The software, in a nutshell, is used to create and store 3D replicas of an object in a digital form.

The tension in the room shot up as participants tried to complete the maximum number of figures on their computers faster than one can say Jack Robinson. The first round had two slots – each an hour and a half long. Participation was minimal.

The second round kicked it up a notch. The questions were designed to test their ability to further visualise the models. Nine teams were selected with no more than three on each. Unlike round one, the brawl had to be fought and won by making three kinds of digital replicas on CATIA in an astounding manner. The first question comprised of a working fishing boat with practical and applicable designs. That made the participants hunt high and low about concepts of fluid mechanics, safety requirements – to later combine them with the structure of the boat to separate it from its fictional constraints.

The second question had a complex diagram on a sheet of paper. Correspondingly, the third was a physical model of a nut-bolt arrangement shown to them.

Staying true to TechTatva’s theme, Mechanics Assemble used a software that can make fictional diagrams real. Giving a unique insight Ujwal, the Co-Event Head, claimed that limitations tied to design, cost, or application can be realized by designing models in CATIA. It saves the need to make physical models to do various tests and analysis
